Abstract (en)

[origin: WO2022096509A1] The invention relates to a method for determining a distance using a high-resolution method based on signal propagation time measurements. The process of determining distances from wireless signals with a high degree of precision using mathematical methods is known, for example using MUSIC or CAPON or methods such as those from EP 3 564 707, EP 3 502 736 A1, or EP 2 212 705. These methods, however, normally require phase measurements. The aim of the invention is to allow such methods to be used even purely with propagation time measurements. This is achieved in that complex numbers are constructed from propagation time measurements and amplitude measurements or power measurements, said complex numbers allowing the use of known methods.
